 <h2>NAME</h2>
 <div class="sectionbody">
 <p>git-remote-helpers -
  Helper programs for interoperation with remote git
 </p>
 </div>
 </div>
 <h2>SYNOPSIS</h2>
 <div class="sectionbody">
 <div class="para"><p><em>git remote-&lt;transport&gt;</em> &lt;remote&gt;</p></div>
 </div>
 <h2 id="_description">DESCRIPTION</h2>
 <div class="sectionbody">
 <div class="para"><p>These programs are normally not used directly by end users, but are
 invoked by various git programs that interact with remote repositories
 when the repository they would operate on will be accessed using
 transport code not linked into the main git binary. Various particular
 helper programs will behave as documented here.</p></div>
 </div>
 <h2 id="_commands">COMMANDS</h2>
 <div class="sectionbody">
 <div class="para"><p>Commands are given by the caller on the helper's standard input, one per line.</p></div>
 <div class="vlist"><dl>
 <dt>
 <em>capabilities</em>
 </dt>
 <dd>
 <p>
  Lists the capabilities of the helper, one per line, ending
  with a blank line.
 </p>
 </dd>
 <dt>
 <em>list</em>
 </dt>
 <dd>
 <p>
  Lists the refs, one per line, in the format "&lt;value&gt; &lt;name&gt;
  [&lt;attr&gt; &#8230;]". The value may be a hex sha1 hash, "@&lt;dest&gt;" for
  a symref, or "?" to indicate that the helper could not get the
  value of the ref. A space-separated list of attributes follows
  the name; unrecognized attributes are ignored. After the
  complete list, outputs a blank line.
 </p>
 <div class="para"><p>If <em>push</em> is supported this may be called as <em>list for-push</em>
 to obtain the current refs prior to sending one or more <em>push</em>
 commands to the helper.</p></div>
 </dd>
 <dt>
 <em>option</em> &lt;name&gt; &lt;value&gt;
 </dt>
 <dd>
 <p>
  Set the transport helper option &lt;name&gt; to &lt;value&gt;. Outputs a
  single line containing one of <em>ok</em> (option successfully set),
  <em>unsupported</em> (option not recognized) or <em>error &lt;msg&gt;</em>
  (option &lt;name&gt; is supported but &lt;value&gt; is not correct
  for it). Options should be set before other commands,
  and may how those commands behave.
 </p>
 <div class="para"><p>Supported if the helper has the "option" capability.</p></div>
 </dd>
 <dt>
 <em>fetch</em> &lt;sha1&gt; &lt;name&gt;
 </dt>
 <dd>
 <p>
  Fetches the given object, writing the necessary objects
  to the database. Fetch commands are sent in a batch, one
  per line, and the batch is terminated with a blank line.
  Outputs a single blank line when all fetch commands in the
  same batch are complete. Only objects which were reported
  in the ref list with a sha1 may be fetched this way.
 </p>
 <div class="para"><p>Optionally may output a <em>lock &lt;file&gt;</em> line indicating a file under
 GIT_DIR/objects/pack which is keeping a pack until refs can be
 suitably updated.</p></div>
 <div class="para"><p>Supported if the helper has the "fetch" capability.</p></div>
 </dd>
 <dt>
 <em>push</em> +&lt;src&gt;:&lt;dst&gt;
 </dt>
 <dd>
 <p>
  Pushes the given &lt;src&gt; commit or branch locally to the
  remote branch described by &lt;dst&gt;. A batch sequence of
  one or more push commands is terminated with a blank line.
 </p>
 <div class="para"><p>Zero or more protocol options may be entered after the last <em>push</em>
 command, before the batch's terminating blank line.</p></div>
 <div class="para"><p>When the push is complete, outputs one or more <em>ok &lt;dst&gt;</em> or
 <em>error &lt;dst&gt; &lt;why&gt;?</em> lines to indicate success or failure of
 each pushed ref. The status report output is terminated by
 a blank line. The option field &lt;why&gt; may be quoted in a C
 style string if it contains an LF.</p></div>
 <div class="para"><p>Supported if the helper has the "push" capability.</p></div>
 </dd>
 <dt>
 <em>import</em> &lt;name&gt;
 </dt>
 <dd>
 <p>
  Produces a fast-import stream which imports the current value
  of the named ref. It may additionally import other refs as
  needed to construct the history efficiently. The script writes
  to a helper-specific private namespace. The value of the named
  ref should be written to a location in this namespace derived
  by applying the refspecs from the "refspec" capability to the
  name of the ref.
 </p>
 <div class="para"><p>Supported if the helper has the "import" capability.</p></div>
 </dd>
 </dl></div>
 <div class="para"><p>If a fatal error occurs, the program writes the error message to
 stderr and exits. The caller should expect that a suitable error
 message has been printed if the child closes the connection without
 completing a valid response for the current command.</p></div>
 <div class="para"><p>Additional commands may be supported, as may be determined from
 capabilities reported by the helper.</p></div>
 </div>
 <h2 id="_capabilities">CAPABILITIES</h2>
 <div class="sectionbody">
 <div class="vlist"><dl>
 <dt>
 <em>fetch</em>
 </dt>
 <dd>
 <p>
  This helper supports the <em>fetch</em> command.
 </p>
 </dd>
 <dt>
 <em>option</em>
 </dt>
 <dd>
 <p>
  This helper supports the option command.
 </p>
 </dd>
 <dt>
 <em>push</em>
 </dt>
 <dd>
 <p>
  This helper supports the <em>push</em> command.
 </p>
 </dd>
 <dt>
 <em>import</em>
 </dt>
 <dd>
 <p>
  This helper supports the <em>import</em> command.
 </p>
 </dd>
 <dt>
 <em>refspec</em> <em>spec</em>
 </dt>
 <dd>
 <p>
  When using the import command, expect the source ref to have
  been written to the destination ref. The earliest applicable
  refspec takes precedence. For example
  "refs/heads/<strong>:refs/svn/origin/branches/</strong>" means that, after an
  "import refs/heads/name", the script has written to
  refs/svn/origin/branches/name. If this capability is used at
  all, it must cover all refs reported by the list command; if
  it is not used, it is effectively "<strong>:</strong>"
 </p>
 </dd>
 </dl></div>
 </div>
 <h2 id="_ref_list_attributes">REF LIST ATTRIBUTES</h2>
 <div class="sectionbody">
 <div class="vlist"><dl>
 <dt>
 <em>for-push</em>
 </dt>
 <dd>
 <p>
  The caller wants to use the ref list to prepare push
  commands. A helper might chose to acquire the ref list by
  opening a different type of connection to the destination.
 </p>
 </dd>
 <dt>
 <em>unchanged</em>
 </dt>
 <dd>
 <p>
  This ref is unchanged since the last import or fetch, although
  the helper cannot necessarily determine what value that produced.
 </p>
 </dd>
 </dl></div>
 </div>
 <h2 id="_options">OPTIONS</h2>
 <div class="sectionbody">
 <div class="vlist"><dl>
 <dt>
 <em>option verbosity</em> &lt;N&gt;
 </dt>
 <dd>
 <p>
  Change the level of messages displayed by the helper.
  When N is 0 the end-user has asked the process to be
  quiet, and the helper should produce only error output.
  N of 1 is the default level of verbosity, higher values
  of N correspond to the number of -v flags passed on the
  command line.
 </p>
 </dd>
 <dt>
 <em>option progress</em> {<em>true</em>|<em>false</em>}
 </dt>
 <dd>
 <p>
  Enable (or disable) progress messages displayed by the
  transport helper during a command.
 </p>
 </dd>
 <dt>
 <em>option depth</em> &lt;depth&gt;
 </dt>
 <dd>
 <p>
  Deepen the history of a shallow repository.
 </p>
 </dd>
 <dt>
 <em>option followtags</em> {<em>true</em>|<em>false</em>}
 </dt>
 <dd>
 <p>
  If enabled the helper should automatically fetch annotated
  tag objects if the object the tag points at was transferred
  during the fetch command. If the tag is not fetched by
  the helper a second fetch command will usually be sent to
  ask for the tag specifically. Some helpers may be able to
  use this option to avoid a second network connection.
 </p>
 </dd>
 </dl></div>
 <div class="para"><p><em>option dry-run</em> {<em>true</em>|<em>false</em>}:
  If true, pretend the operation completed successfully,
  but don't actually change any repository data. For most
  helpers this only applies to the <em>push</em>, if supported.</p></div>

	</div>
	<h2 id="_description">DESCRIPTION</h2>
	<div class="sectionbody">
	<div class="para"><p>These programs are normally not used directly by end users, but are
	invoked by various git programs that interact with remote repositories
	when the repository they would operate on will be accessed using
	transport code not linked into the main git binary. Various particular
	helper programs will behave as documented here.</p></div>
	</div>
	<h2 id="_commands">COMMANDS</h2>
	<div class="sectionbody">
	<div class="para"><p>Commands are given by the caller on the helper's standard input, one per line.</p></div>
	<div class="vlist"><dl>
	<dt>
	<em>capabilities</em>
	</dt>
	<dd>
	<p>
	Lists the capabilities of the helper, one per line, ending
	with a blank line.
	</p>
	</dd>
	<dt>
	<em>list</em>
	</dt>
	<dd>
	<p>
	Lists the refs, one per line, in the format "<value> <name>
	[<attr> …]". The value may be a hex sha1 hash, "@<dest>" for
	a symref, or "?" to indicate that the helper could not get the
	value of the ref. A space-separated list of attributes follows
	the name; unrecognized attributes are ignored. After the
	complete list, outputs a blank line.
	</p>
	<div class="para"><p>If <em>push</em> is supported this may be called as <em>list for-push</em>
	to obtain the current refs prior to sending one or more <em>push</em>
	commands to the helper.</p></div>
	</dd>
	<dt>
	<em>option</em> <name> <value>
	</dt>
	<dd>
	<p>
	Set the transport helper option <name> to <value>. Outputs a
	single line containing one of <em>ok</em> (option successfully set),
	<em>unsupported</em> (option not recognized) or <em>error <msg></em>
	(option <name> is supported but <value> is not correct
	for it). Options should be set before other commands,
	and may how those commands behave.
	</p>
	<div class="para"><p>Supported if the helper has the "option" capability.</p></div>
	</dd>
	<dt>
	<em>fetch</em> <sha1> <name>
	</dt>
	<dd>
	<p>
	Fetches the given object, writing the necessary objects
	to the database. Fetch commands are sent in a batch, one
	per line, and the batch is terminated with a blank line.
	Outputs a single blank line when all fetch commands in the
	same batch are complete. Only objects which were reported
	in the ref list with a sha1 may be fetched this way.
	</p>
	<div class="para"><p>Optionally may output a <em>lock <file></em> line indicating a file under
	GIT_DIR/objects/pack which is keeping a pack until refs can be
	suitably updated.</p></div>
	<div class="para"><p>Supported if the helper has the "fetch" capability.</p></div>
	</dd>
	<dt>
	<em>push</em> +<src>:<dst>
	</dt>
	<dd>
	<p>
	Pushes the given <src> commit or branch locally to the
	remote branch described by <dst>. A batch sequence of
	one or more push commands is terminated with a blank line.
	</p>
	<div class="para"><p>Zero or more protocol options may be entered after the last <em>push</em>
	command, before the batch's terminating blank line.</p></div>
	<div class="para"><p>When the push is complete, outputs one or more <em>ok <dst></em> or
	<em>error <dst> <why>?</em> lines to indicate success or failure of
	each pushed ref. The status report output is terminated by
	a blank line. The option field <why> may be quoted in a C
	style string if it contains an LF.</p></div>
	<div class="para"><p>Supported if the helper has the "push" capability.</p></div>
	</dd>
	<dt>
	<em>import</em> <name>
	</dt>
	<dd>
	<p>
	Produces a fast-import stream which imports the current value
	of the named ref. It may additionally import other refs as
	needed to construct the history efficiently. The script writes
	to a helper-specific private namespace. The value of the named
	ref should be written to a location in this namespace derived
	by applying the refspecs from the "refspec" capability to the
	name of the ref.
	</p>
	<div class="para"><p>Supported if the helper has the "import" capability.</p></div>
	</dd>
	</dl></div>
	<div class="para"><p>If a fatal error occurs, the program writes the error message to
	stderr and exits. The caller should expect that a suitable error
	message has been printed if the child closes the connection without
	completing a valid response for the current command.</p></div>
	<div class="para"><p>Additional commands may be supported, as may be determined from
	capabilities reported by the helper.</p></div>

	<div class="sectionbody">
	<div class="vlist"><dl>
	<dt>
	<em>fetch</em>
	</dt>
	<dd>
	<p>
	This helper supports the <em>fetch</em> command.
	</p>
	</dd>
	<dt>
	<em>option</em>
	</dt>
	<dd>
	<p>
	This helper supports the option command.
	</p>
	</dd>
	<dt>
	<em>push</em>
	</dt>
	<dd>
	<p>
	This helper supports the <em>push</em> command.
	</p>
	</dd>
	<dt>
	<em>import</em>
	</dt>
	<dd>
	<p>
	This helper supports the <em>import</em> command.
	</p>
	</dd>
	<dt>
	<em>refspec</em> <em>spec</em>
	</dt>
	<dd>
	<p>
	When using the import command, expect the source ref to have
	been written to the destination ref. The earliest applicable
	refspec takes precedence. For example
	"refs/heads/<strong>:refs/svn/origin/branches/</strong>" means that, after an
	"import refs/heads/name", the script has written to
	refs/svn/origin/branches/name. If this capability is used at
	all, it must cover all refs reported by the list command; if
	it is not used, it is effectively "<strong>:</strong>"
	</p>
	</dd>
	</dl></div>
	</div>
	<h2 id="_ref_list_attributes">REF LIST ATTRIBUTES</h2>
	<div class="sectionbody">
	<div class="vlist"><dl>
	<dt>
	<em>for-push</em>
	</dt>
	<dd>
	<p>
	The caller wants to use the ref list to prepare push
	commands. A helper might chose to acquire the ref list by
	opening a different type of connection to the destination.
	</p>
	</dd>
	<dt>
	<em>unchanged</em>
	</dt>
	<dd>
	<p>
	This ref is unchanged since the last import or fetch, although
	the helper cannot necessarily determine what value that produced.
	</p>
	</dd>
	</dl></div>
	</div>
	<h2 id="_options">OPTIONS</h2>
	<div class="sectionbody">
	<div class="vlist"><dl>
	<dt>
	<em>option verbosity</em> <N>
	</dt>
	<dd>
	<p>
	Change the level of messages displayed by the helper.
	When N is 0 the end-user has asked the process to be
	quiet, and the helper should produce only error output.
	N of 1 is the default level of verbosity, higher values
	of N correspond to the number of -v flags passed on the
	command line.
	</p>
	</dd>
	<dt>
	<em>option progress</em> {<em>true</em>\|<em>false</em>}
	</dt>
	<dd>
	<p>
	Enable (or disable) progress messages displayed by the
	transport helper during a command.
	</p>
	</dd>
	<dt>
	<em>option depth</em> <depth>
	</dt>
	<dd>
	<p>
	Deepen the history of a shallow repository.
	</p>
	</dd>
	<dt>
	<em>option followtags</em> {<em>true</em>\|<em>false</em>}
	</dt>
	<dd>
	<p>
	If enabled the helper should automatically fetch annotated
	tag objects if the object the tag points at was transferred
	during the fetch command. If the tag is not fetched by
	the helper a second fetch command will usually be sent to
	ask for the tag specifically. Some helpers may be able to
	use this option to avoid a second network connection.
	</p>
	</dd>
	</dl></div>
	<div class="para"><p><em>option dry-run</em> {<em>true</em>\|<em>false</em>}:
	If true, pretend the operation completed successfully,
	but don't actually change any repository data. For most
	helpers this only applies to the <em>push</em>, if supported.</p></div>
